# Hide elements via selectors.
#
# Works wonderfully to block facebook ads which are
# pre-loaded ;o zomg
#
# Probably won't often update this gist, but selectors
# simply need to be added to @patterns
# 
# You can avoid the transpile if you run this using
# the Injector, chrome extension. s'what I use.
